SPECIFICATION formihg part of Letters Patent no. serale, atea April 17, 1898.

Application tiled January 301888. Serial No. 262,330. (No model.)

To all whom it may concern:

Be it known that I, FRANK P. BARNEY, a citizen of the United States, residing at Chartley, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements-in Buttons; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention relates to that class of cuff'- buttons in which the shoe is pivotally connected 4with the shank or post, so that said shoe may be brought in lin-e with said post for passing it through the button-holes, proper stops being provided to prevent theshoe from tilting in both directions. l

The invention has for its object to simplify the construction of such buttons, thereby re'- ducing the labor connected with their manufacture; and said invention consists in structural features and combinations of parts, substantially as hereinafter fully described and claimed. g

In this class of buttons as heretofore constructedas,for intance, the button described in Letters 'Patent No. 358,384, of February 21, 1887-the shoe is composed of an outer shell, an inner plate or disk, in or on which are formed four abutments or shoulders between which the cross-head of the shank or post is confined, and a spring plate or disk slotted from its center toward the periphery, through which the cross-head'of the post or shank passes and that serves to hold the shoe in the position into which it is brought relatively to the shank.

I have found thatequally as good resultscan be attained by using a plain concavo-convex intermediate or abutting disk and by dispensing with two of the shoulders or abutments for the cross-head of the shank. This I attain by forming two abutments on opposite sides of the slot in the spring plateor disk, at such a distance from that end of the slot-nearest the periphery of the disk to accommodate the neck of the shank,` thebearings on one side of the cross-'head being formed by said two projections or shoulders, and for the other side by the end of the slot-that is to say, the `end of the slot and the shoulders or abutments hold the post against displacement in the slot of the spring-plate,which slot has to be sufciently long to permit of said spring-plate Vbeing slipped over the cross-head onto the shank. In this manner at one operation I am enabled to slot the spring plate or disk and form the tWdabutments thereon by transverse slitting and forcing out the metal. But that my invention may be better understood I will describe the same with reference to the accompanying drawings,in which like letters indicate like parts wherever such may occurin the various figures. v A

Figure 1 is an elevation of the button,show ing lthe shoe tilted on a line with the shank. Fig. 2 is a like View, the outer shell and intermediate co'ncavo-convex disk being removed, showing the position of the cross-head of the shank in its bearings in the spring disk or plate. Fig. 3 is a vertical section on line w x of Fig. 1.` Fig. 4 is anisometric view of the spring plate or disk. Figs. 5 and 6 are elevations of the intermediate disk and shell'of the shoe; and Fig. 7 is an isometric view of the button-head and shank. y

A indicates the button-head; a, the post or shank that is provided vwith a cross-head, a', bent over at right angles to the shank,or nearly so.

The upper end of the post on which the crosshead a is formed is of reduced width, so as to kform shoulders a2, upon which theshoe rests the shank a, as is usual.

The shoe B consists of a shell, b, a concaveconvex disk, b', fitting into said shell, and on which the cross-head a. of the shank a bears, and of the spring plate or disk C. This disk has formed in it a longitudinal slot, c, extending from the center of the disk toward the periphery thereof,and is of such length as to admit of the plate being slipped over the crosshead onto the shank a of the button-head A, then turned to bring the sloton a line with the upper reduced 4and bent-over lportion of the shank a, which in its normal position lies in when brought into a position at right angles to thatend of the slot c nearest to the periphery of the disk C.

To prevent the shoe from slipping or sliding ou t-he c'ross-head,and also to prevent said shoe from tilting to both sides of the shank a, I form on opposite sides of the slotc a shoulder, c', by slitting the disk and forcing out the metal. These shoulders areatsuch a distance from that end of the slot nearest to the periphery of the disk C as to leave sufficient space to accommodate the cross-head a', and thus confine the shoe to the shank, as hereinbefore stated, and prevent said shoe from slipping on said shank when tilted. l

It is obvious that the construction of the tilting shoe is an exceedingly simple one; yet the shoe is firmly held to the shank whatever position it may be brought in, the cross-head being, as usual, rectangular in crosssection,or provided witha dat bearing-surface, a3, against which bears the intermediate concavo-convex disk, b.

In Lthe assembling of the parts of the shoe the spring-plate is slipped on the shank a of the button-head A, as above described. The plain disk b is inserted into the shell b. Then the spring plate or disk C is inserted and the of the shell b, the concavo-convex disk b', and

the slotted disk' C, provided with the two shoulders or abutments c', formed by slitting the disk on opposite sides of the Vslot c and forcing out the metal, said parts being con structed and arranged substantially as described, for the purposes specified.

In testimony whereof I aix my signature in presence of two witnesses.
